wanhao d7 or plus or box nanodlp installation and profile nanopi m1 and raspberry

thingiverse

Wanhao printers with the display and the external boxes already have a processor board similar to raspberry pi, and thanks to linux arm version of nanodlp is possible to use the original board without purchasing a new raspberry. I have added a full working machine profile, that i think work also in the raspberry version, it work only if the correct z travel is setted to 198mm via the gcode "M206 T3 P153 X198" command. I have also added a static time profile, but have some problems when resume print from stop, skip some layers because the start curing time start from the initial z axix movement. This is all the necessary for install nanodlp on original nanopi m1 board from wanhao d7 plus or wanhao d7 external box (is the same), the dgus display isn't compatible, is possible to mount a nextion display: * all information on the board for possibe connection of the tft display that in the d7 plus is already connected with an header on the uart1 /dev/ttyS1 (like on raspberry), but is a dwin dgus display. The header is the same of raspberry, i think that is possible to use also i2c bus: - http://wiki.friendlyarm.com/wiki/index.php/NanoPi_M1 * Armbian_20.02.1_Nanopim1_buster_current_5.4.20 on sd (with hddrawcopy or balenaeatch or win32diskimage), after bootloader load the kernel the blue led blink, at the first start the filesystem is automatically extended DON'T INTERRUPT - https://www.armbian.com/nanopi-m1/ * connect via ssh to the ip addres (with putty) of the board and login (root, 1234), after create user d7 * open armbian-config in the terminal and change this values: - the cpu by default is overclocked to 1.39ghz, set the governor to 480-1200 on demand for the stock cpu specs - change the line in the bootenv for disable video console that is set "both" to default: * console=serial - add this line at last to the bootenv for disable blinking cursor: * extraargs=vt.global_cursor_default=0 - enable on the peripherals all usbhosts and all uarts (this require a reboot, you can do it later) - change locale to your language, timezone and keyboard map - install avahi - execute firmware update (this command lanch apt-get update and upgrade automatically) * reboot (with reboot command, not detach power) and login with d7 user * install this packages with aptitude: - sudo apt-get install libpng-dev libpng16-16 * usbmount isn't present in the repository and you have to compile it with dpkg if you use the usb with this commands: - cd /usr/src/ - sudo git clone http://github.com/kgara/usbmount/ --depth 1 - sudo apt-get install debhelper lockfile-progs - cd ./usbmount - sudo dpkg-buildpackage -us -uc -b - sudo dpkg -i ../usbmount_0.0.24_all.deb * put the console on the home of d7: - cd /home/d7 * download nanodlp - wget http://www.nanodlp.com/download/nanodlp.arm.zip * unzip with - unzip ./nanodlp.arm.zip -d ./nanodlp * create a file with nano like this and save it: - sudo nano /etc/systemd/system/nanodlp.service --------------------file content---------------------- - [Unit] - Description=NanoDLP service - After=systemd-user-sessions.service plymouth-quit-wait.service - - [Service] - WorkingDirectory=/home/d7/nanodlp - ExecStart=/bin/bash /home/d7/nanodlp/run.sh - Restart=always - RestartSec=5 - - [Install] - WantedBy=multi-user.target * enable the service with - sudo systemctl --now enable nanodlp * the web interface is now accessible * update to the latest beta via the tools page/update nanodlp * flash the firmware D7_v1-3.hex firmware (the same on the wanhao site and the wiki) * restore the setup-nanodlp-d7.json machine profile through tools on web interface * after ramps is connected send this line to it by ramps terminal: - M206 T3 P153 X198 * import the profile-static-example.json profile example from resin profiles * you can connect the dx fan (for nanopi) on the 12v white connector on the board, and the sx fan (for ramps) with uv fan to output screw terminals. In this way the uv and ramps fans power up only when printing, that is more logic.
